Remote control processor
The remote control processor on the HP-IB/MS control card synchronizes start-
run signals with GCs and other devices. The functions of the remote control pro-
cessor are extended to the remote start (
Remote) connector on the back panel of
the MSD. The remote start cable connects the GC and the MSD.
Remote start signals
It is often necessary to communicate with external devices (for example, a purge-
and-trap) during a run. Typically, these communications are:
• Requests to send a system ready signal
• Receive a start run signal from an external device
• Program the timing of events during a run
